4.12 Standalone Reconfiguration
To access the circuit board on a standalone unit, the enclosure cover must first be removed by
loosening the six screws on the sides of the unit. Next, unplug the power supply connector from
the PC board, and remove the two screws holding the rear panel in place.
The entire circuit board can now be removed by loosening the eight mounting screws. The
interface board can now be changed as covered in section 4.11.
The rear panel supplied with the new interface must also be exchanged with the original rear
panel. The unit can then be assembled in the reverse order of the disassembly.
